A heartline roll on a pipeline roller coaster, where the car is located between the rails

A heartline roll (sometimes called a barrel roll) is a roller coasterinversion in which the rider performs a 360 degree roll on one axis. Unlike an in-line twist, the elevation of the track changes throughout the inversion to keep the train travelling at the same level.

While usually existing on their own, multiple heartline rolls can be strung together. Double heartline rolls feature on Typhoon, a Gerstlauer Euro-Fighter installation, and Outlaw Run, a Rocky Mountain Constructionwooden roller coaster. Intamin have included triple and quadruple heartline rolls on their 8-Looping and 10-Looping coasters respectively.
